Each of two urns contains green balls and red balls. urn 1 contains 10 green balls and 14 red balls. urn 2 contains 4 green balls and 11 red balls. if a ball is drawn from each urn what is p(red and red)?
BTW- i really don't know what an urn is, i guess a basket or some small bag, but its not important anyway.here are the answer choices:
a.1/9
b.25/39
c.79/60
d.77/180
i think its b. PLz help when you get the chance and thank you for your time. :)
no, the events are independent, so you multiply the probabities of each event
urn1, prob(red) = 14/24
urn2, prob(red) = 11/15
prob(red and red) = (14/25)(11/15) = 77/180
btw, an urn is an ancient clay pot or jug.
e.g. read: Ode on a Grecian Urn by John Keats
77/180. I dub this…correct!
Urns are what people used to put other people's ashes in. (After they burnt the person.):D I play Skyrim. xD
I don't even have that answer choice, is this correct???
Urns are what people use to put other people's ashes in. My Grandpa was a heavy smoker and now is a silver urn to the left of my fireplace (The irony):D I don't play Skyrim. xP
well that escalated quickly

I couldn't find correct answers alltogether, so I searched them one by one. I got a 66%. I go to Connexus Academy and after any assignment they show the correct answer. This what i got above. I think this should be correct for a while before they change the answers again. Btw this is the Probability Unit Test Part 1. Good Luck!!!! :)
I was just trying to get answers but other dictators were commenting so...
^ O_O WOW
oh cool thanks for the help and xtra info!
So close my questions are a little bit different but SOOO close but thanks for the help
Whether you do the deed of killing or have someone do it it's the same thing. As long as we lean from the bad part of history and move on that is all that matters. We all need to make a better and safer place for our friends and family.
What the plop
is he right i go to texas
Each of two urns contains green balls and red balls. Urn I contains 10 green balls and 14 red balls. Urn II contains 4 green balls and 11 red balls. If a ball is drawn from each urn, what is P(red and red)?
A. one ninth
B. 25 over 39
C. 79 over 60
D. 77 over 180
The probability of drawing a red ball from urn I is 14/24. The probability of drawing a red ball from urn II is 11/15. Since the events are independent, the probability of both events occurring is the product of their individual probabilities. Therefore, P(red and red) = (14/24) x (11/15) = 77/180. The correct answer is D.
A drawer contains 2 red socks, 3 white socks, and 3 blue socks. Without looking, you draw out a sock, return it, and draw out a second sock. What is the probability that the first sock is blue and the second sock is red?
The probability of drawing a blue sock on the first draw is 3/8. After replacing the sock, there are still 2 red socks in the drawer out of a total of 8 socks. Therefore, the probability of drawing a red sock on the second draw is 2/8 or 1/4. Since these events are independent, the probability of both events occurring is the product of their individual probabilities.
Therefore, P(blue and red) = (3/8) x (1/4)
= 3/32
= 0.09375 or about 9.4%
The probability that the first sock is blue and the second sock is red is approximately 9.4%.
9.4 as a fraction
9.4 expressed as a fraction is 94/10 or 47/5 in simplest form.
From a barrel of colored marbles, you randomly select 3 blue, 2 yellow, 7 red, 8 green, and 2 purple marbles. Find the experimental probability of randomly selecting either a green or a purple marble
The number of green and purple marbles in the barrel is 8 + 2 = 10.
The total number of marbles in the barrel is 3 + 2 + 7 + 8 + 2 = 22.
The experimental probability of selecting a green or a purple marble can be found by dividing the number of green and purple marbles by the total number of marbles:
Probability = Number of desired outcomes / Number of possible outcomes
Probability of selecting a green or a purple marble = 10/22 = 5/11
Therefore, the experimental probability of randomly selecting either a green or a purple marble is 5/11.
A number cube is rolled 360 times and the results are recorded as follows: 54 ones, 60 twos, 55 threes, 71 fours, 35 fives, 74 sixes. What is the experimental probability of rolling a two or a three?
The number of times a two or a three is rolled is the sum of the number of times a two is rolled and the number of times a three is rolled, which is 60 + 55 = 115 times.
The total number of rolls is 360.
The experimental probability of rolling a two or a three can be found by dividing the number of times a two or a three is rolled by the total number of rolls:
Probability = Number of desired outcomes / Number of possible outcomes
Probability of rolling a two or a three = 115/360
Therefore, the experimental probability of rolling a two or a three is 23/72.
23/72 as a decimal
To convert 23/72 to a decimal, divide the numerator by the denominator:
23 ÷ 72 = 0.3194 (rounded to four decimal places)
Therefore, 23/72 as a decimal is approximately 0.3194.
A standard number cube with the numbers 1 through 6 is rolled. Find the probability of rolling a number less then 3. Find the probability of not rolling a number less then 3
There are two numbers less than 3 on a standard number cube: 1 and 2.
The probability of rolling a number less than 3 is the sum of the probabilities of rolling a 1 and rolling a 2:
P(rolling a number less than 3) = P(rolling a 1) + P(rolling a 2) = 1/6 + 1/6 = 2/6 = 1/3.
Therefore, the probability of rolling a number less than 3 is 1/3.
The probability of not rolling a number less than 3 is the probability of rolling a number greater than or equal to 3:
P(not rolling a number less than 3) = P(rolling a 3) + P(rolling a 4) + P(rolling a 5) + P(rolling a 6) = 1/6 + 1/6 + 1/6 + 1/6 = 4/6 = 2/3.
Therefore, the probability of not rolling a number less than 3 is 2/3.
A bag contains 6 red marbles, 3 white marbles, and 7 blue marbles. You pick a marble without looking. Find the probability of drawing a white marble
There are a total of 6 + 3 + 7 = 16 marbles in the bag.
The probability of drawing a white marble can be found by dividing the number of white marbles by the total number of marbles:
Probability = Number of desired outcomes / Number of possible outcomes
Probability of drawing a white marble = 3/16
Therefore, the probability of drawing a white marble from the bag is 3/16.
A standard number cube is rolled 180 times. Predict how many times a 3 or a 5
There are two numbers on a standard cube that are either 3 or 5, so the probability of rolling a 3 or a 5 on any given roll is:
P(rolling a 3 or a 5) = P(rolling a 3) + P(rolling a 5) = 1/6 + 1/6 = 1/3
To predict how many times a 3 or a 5 is rolled in 180 rolls, we can multiply the number of rolls by the probability of rolling a 3 or a 5:
Number of 3's or 5's rolled = (Number of rolls) x P(rolling a 3 or a 5)
Number of 3's or 5's rolled = 180 x (1/3)
Number of 3's or 5's rolled = 60
Therefore, we can predict that a 3 or a 5 will be rolled approximately 60 times in 180 rolls.
